//引入axios
import axios from 'axios'
//配置axios的全局基本路径

// 将axios对象作为Vue的扩展对象

//1.axios前置拦截器：每次通过axios发送请求之前，让所有的请求都携带uToken
axios.interceptors.request.use(config=>{
  //携带token
  let token =  localStorage.getItem("token");
  if(token){
    config.headers['token']=token;
  }
  return config;
},error => {
  Promise.reject(error);
})


//3 使用axios后置拦截器，处理没有登录请求
axios.interceptors.response.use(res => {
  //后端响应的是没有登录的信息
  if (false === res.data.success && "noLogin" === res.data.message) {
    localStorage.removeItem("token");
    localStorage.removeItem("logininfo");
    router.push({path: '/login'});
  }
  return res;
},error => {
  Promise.reject(error)
})

//======================路由的前端拦截器【拦截不到后端的请求】====================//
//注释掉登陆拦截：判断session中有没有user对象并且路径不是login就调转到登录页面
router.beforeEach((to, from, next) => {
  //如果访问登录页面   或  注册页面
  if (to.path == '/login' || to.path == "/register") {
    next();//放行
  }else{//其他页面都需要判断你是否登录过
    let logininfo = localStorage.getItem('logininfo');
    if (logininfo) {
      next(); //登录过放行
    } else {
      next({path: '/login'});//跳转到login - 登录页面
    }
  }
})

new Vue({
  //el: '#app',
  //template: '<App/>',
  router,
  store,
  //components: { App }
  render: h => h(App)
}).$mount('#app')
